Well, this thread has been quite an eye-opener.
None of the COs that I knew were particularly wealthy. I never saw any of them receiving cash gifts, but then I don't think it would be any different from Christendom's leaders receiving personal gifts for the work they do.
Being a CO in the JW world is looked up to being a spiritual giant. It was something that some pioneers/Bethelites aspired to. Their lifestyle is like one of a travelling salesman, although instead of being accomodated in hotels the CO and his wife have a caravan or stay with other bros & sisters. Some have their own home, bought and paid for before they went on the Circuit work.
Never heard of them going on overseas trips either. If someone wants to shout them to a overseas trip, good luck to them. At the end of their circuit "career", they're not going to be left with much, so they might as well enjoy what they can get while they can.
I am curious about some of the attitudes expressed towards COs. Is it because of personal run-ins with them? Most of the COs I knew were good people, some were even good friends of my parents. COs were regarded as being like travelling shepherds of the congregation. A spiritual guide who had more oomph than the congregation's elders. Of course, as I became more disenchanted with the JWs my reverance for them dwindled, and I came to see them as mere men with no more special enlightenment than Joe Nobody in the cong. Now, I feel pity for them, because they think that they are serving God and that what they are doing is a special work.
